What energy efficiency ratings mean and why theyre important

January 10, 2017

The cost to heat and cool your home totals more than half of your utility bills. That’s why it’s crucial to look for a system that provides quality comfort in your Rocky Mount home while still remaining energy efficient. Greater energy efficiency means your system is operating well while using less energy. Whether you are thinking about a replacement air conditioner or furnace or thinking to upgrade your present equipment to be more energy efficient, there are some ratings to be aware of that will help you during the procedure. So what exactly do those energy efficiency ratings indicate?

SEER (used to measure cooling efficiency)
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating takes into consideration the efficiency of your unit at different temperatures, meaning, seasonally in Rocky Mount. A larger SEER rating signifies a larger energy efficiency, which will convert into smaller utility bills. The Department of Energy expects a minimum 13 SEER-rating for chillier states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an aged unit with a lower SEER-rating, you could see drastic energy savings after an modern system.

AFUE or HSPF (used to measure heating efficiency: gas or electric)
AFUE stands for Annualized Fuel Utilization Efficiency ratio and it finds the percentage of heat created for every dollar of fuel expended. You can consider it as the MPG on your car. The larger the AFUE-rating, the less your energy costs. If your furnace has a AFUE rating of 80, that means that 80% of the heat generated is used to heat the home, while 20% of the heat is lost through venting.

HSPF stands for the Heating Seasonal Performance Factor and is used to determine the heating effectiveness of heat pumps. It is the SEER rating for the winter season as it only keeps track of your unit’s heating productivity. Similarly, the higher the number, the more energy efficient the heat pump.
